IMPROVEMENT IN MACHINES FOR COLORING PAPER.

Specification forming part of Letters Patent No.147,300, dated February 10, 1374; application filed May i4, 1873.

To all whom it may concern:

Be it known that I, CARL WOLLMUTH, of Bethlehem, in the State of Pennsylvania, have invented a new and useful Machine for the Manufacture of an Improved Oil Tall-Paper; and I do hereby declare the following to be a full, clear, and precise description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings which form a part of this specification, and in whichi Figure l is a side elevation of my machine. Fig. 2 is a perspective view of the whole internal mechanism, the side of the frame-work nearest the beholder being removed. Fig. 3 is a partial top view of one of the funnels. Fig. 4 is an end view of the same. Fig. 5 is a view of one of the cam wheels and levers used to give lateral motion to the funnel connected therewith.

- Similar letters of reference indicate corresponding parts in all 1the iigures.

My invention has for its object the perfection of a machine for the manufacture of an even-surfaced, oilcolored, flat-tinted, opaque wallpaper.

The construction of that machine is as follows: Let A in Figure 1 represent one side of any suitable frame-work manufactured in 'an y design, of wood or iron, two of which sides there are connected and braced as most convenient. Running horizontally between the aforesaid sides, and fastened into them by means of a series of bearings, B B B B B, of any shape or description,controlled by adjusting-bolts to alter the tension ofthe paper, are

a number of rollers, of wood or metal, l 2 3 4 5 6 7, free to rotate in their bearings. Around the first of these rollers l is wound `a roll of any ordinary paper suitable for the 1nanufacture of wall-paper-twelve-ounce paper I prefer. From this roller the paper is carried under the roller 2, then up and over 3, then down and under 4, then over 5; then it passes under a funnel, C, hereinafter to be described; then over the roller 6; then under another funnel, l), similar to the former one C; then over the roller 7 5 then on and `forward over the roller S, located horizontally between two uprights, F, forming an extended framework to the machine; then over another roller, 9, similarly located between the uprights G; and, finally, is wound upon the roller E', located between the uprights H, or in any desired manner. Motivepower maybe furnished by hand, foot, or steam applied to the axle of the roller-wheel I, which being thereby rotated, and having attached to it the end of the roll of paper passing over the rollers aforesaid and wound upon roller l, draws the paper through the machine, unrolling it from the roller l and rolling it upon the Passing through slots J, situate in roller E. the frame-work A A, alternately between the rollers 5, 6, and 7, and above the bearings ot' those rollers, are two bars, K K, having attached to them oblong funnels, C D, of any suitable material, by means of the set-screws L, as shown in Figs. 3, 4, and 5. Said funnels may be made in two pieces bolted together at their ends, and having openings at their bottoms, the size of which may be increased or diminished by means of the tighteningI thumb-screw M acting across their tops. The bars K are given a lateral reciprocating motion by means of the following contrivance, shown in detail in Fig. 5. The ends of the bars K are prolonged beyond the frame-work A upon one side, and are attached to the upper ends of levers N, which levers are fulcrumed, at O, upon any convenient pivot, and descend and take into theirregular groove cut in the outside surface of a cam-wheel, l), set out from the side of the framework A, and rotated by means of a belt passing over the pulley E of the pulley-wheel I, by whose rotation it derives its motion, and passing over a pulley, Q, attached to the cam-wheel l). A composition of oil coloring matter is fed into the funnels C D, before described, by means of two openings or slots out in the bottom of a reservoir, It, located directly above the funnels. Said reservoir R is an ordinary tank located upon suitable framework above the rollers and funnels. Beneath the funnels C l) are ltwo gutters, S S, which receive the overflow of the coloring-matter, and, being inclined downward, allow the oil to ow into a second reservoir, T, situated below the rollers and pulleys, whence it is pumped up by the pump U into the upper reservoir and used again. Upon the axle of the roller 1,-beyond one of the bearings, is a grcoved wheel, V, shown in Fig. 2, over which passes theeord W, which attaches to a horizontal lever-arm, X, to which depends a weight, Y, by whose adjustment a regular `tension can be obtained upon the roller l,

thereby regulating the feed ofthe paper. Attached to the frame-work above the roller el is lever Z, which carries a cross-bar which rests upon the roller 5, and, by pressure, smooths and regulates the feed of the paper under the tunnels.

The operation of my machine is as follows: The roll of paper being adjusted and carried through the rollers, and the upper reservoir illed, the power is applied to the axle of the roller-Wheel I in any .manner desired. The paper, as we have described before, is thus drawn through the machine.y time the pulley Q, attached to the cam-wheel P, is rotated by the belt A from the pulley E, and the cam-wheel, also rotating, gives to the ends of the levers N which take into its irregular slot a vibratory motion, which acts reversely upon the bars K carrying the funnels At 'the same- C D, and imparts to them the lateral reciprocating motion before spoken of. The funnels pouring the oil through the apertures in theirl bottoms upon the paper, by the motion thus given to them spread it evenly all over the surface of the paper passing under them.

The arrangement of two or more funnels (for I do not confine myself to two) enables the laying on of two coats in quick succession, a desideratum in my process.

Having thus fully described my invention, what I claim asthat invention, and desire to secure by Letters Patent, is-e- The combination in a wall-paper machine of one or more transversely-reeiproeating funnels for applying the oileoloring matter, the same having sharp edges for scraping and smoothing the color, with a series of adjustable rollers for earryin g and feeding the paper to be coated, substantially as described.
